VALVE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 559,611, dated May 5, 1896.

Application filed `September 28,1895. Serial No. 563,949. (No model)y To all whom, it may concern:

Be it known that I, JOHN N. SANGER, a resident oi Brooklyn Hills, county of Queens, and State of New York, have invented certain new and useful Improvements in Valve Apparatus, of which the following is a specifica tion My invention relates to valve apparatus, and has for its object to produce a slow-closing tank-valve and an efficient overliow apparatus with means for refilling the bowl.

My invention will be understood by reference to the accompanying drawings, in which- Figure l is an elevation, partly broken away and in section, of an apparatus enibodying my invention. Fig. 2 is an enlarged sectional view of a part thereof hereinafter described. Fig. 3 is a section of the valve and stem shown in Figy). Fig. 4 is a section on line i 4 of Fig. showing the wingguides for the valve-stem; and Fig. 5 is an enlarged sectional detail view of the air-inlet-regulating cap.

In the drawings, A represents a watercloset flush-tank adapted for use with my improved valve apparatus. This tank is apertured at a for the passage of the flushingpipe of the closet.

B is a pipe communicating with the flushing-pipe and terminating in a valve-seat b. Branching from the pipe B is a pipe O, which is in communication with an upright standpipe D, apertured, as at zo, with a small aperture or pin-hole. Mounted upon the standpipe D and embracing the same by its lower ring` e is a valve E, which is adapted to rest upon the upper edge d of the stand-pipe. Sliding upon the stand-pipe D is a float F, which embraces the stand-pipe and is operated by the rise and fall of the water in the tank. This float contacts with the lower ring e of the valve E, so as to raise the valve to permit the water in the flush-tank to overiiow into the stand-pipe D and thence by means of pipes O and B into the ushingpipe. This overiiow will take place only when the level of the water in the flush-tank rises above the upper end of the stand-pipe. The rising water carries with it the float F,

which raises the valve E to permit the water to enter the stand-pipe. lVhen the waterlevel has fallen sufeiently, the lioat falling with it will reseat the valve E and the water in the pipes intervening between the tank and the bowl will run into the bowl to refill the same. The flow of this refill water will be slow, being regulated by the small amountof air entering the stand-pipe D through the aperture Rising from the pipe V and seated in lugs b" are upright rods G. These rods are connected at their upper ends by a yoke II, which is pierced at or about the iniddle thereof for the passage of a screw-threaded stein I. Suitable nuts g or other fastening devices serve to hold the yoke Il upon the rods G.

Mounted upon the stem I (see Figs. 2, 3, and 4) is a sleeve J, carrying` wing-guides l 2 3 4c and terminating in a piston K, which is provided with any usual packing 7;. and held by a suitable nut or other fastening device Z. The stem, wingguides, and piston just described constitute one member of my slow-closing valve. The other member consists of a sleeve L, which moves freely upon the wing-guides and is suspended by a yokehanger M, which engages lugs m ou the movable sleeve and stands at an angle to the yoke II. The sleeve L is closed at the bottom by a plate N, which carries a disk, washer, or packing O, which, when the sleeve is in its lowermost position, rests upon the valveseat l1 of the pipe B. p The piston K ts closely in the movable sleeve L, which is provided with apertures o to allow ingress of water into the sleeve above the piston, iu order to keep the packing thereof moist, so that the piston will fit tightly. The movable sleeve L is also surrounded by the usual loose castmetal weight P, which serves to restore the sleeve toits position resting on the valveseat Z7.

Projecting from the plate N of the sleeve is a screw Q, upon which is mounted a cup R. This cup is of less diameter than the valveseat l) and enters the said valve-seat, the interior of the cup forming a cushioning-chamber S for cushioning the valve. Carried upon the upper end of the stem 'i is an internally- TOO considerable distance little or no air will enf ter; but as the cap is screwed olli the stem the number of screw-threads of the stem which enter the cup will be less, and consequently the air will have more opportunity to enter the stem. The amount of air entering the stem at any given time can be thus eiiiciently regulated by adjusting the position of the cap T.

The operation of my slow-closing valve is as follows: The stem and piston are stationary and the sleeve L movable. W'hen it is desired to flush the water-closet, the cord 5 is pulled, which lifts the sleeve through the medium of lever G, which is connected to the hanger M of the sleeve L. IVhen the sleeve L has been raised, the cord 5 maybe released. This raising may be to various heights, but is preferably to the height shown in Fig. 2. The water in the tank A will rush into the pipe B and thence to the flushing-pipe of the closet, and will continue so to run until the sleeve has been rcseated upon the valve-seat b. This reseating will be accomplished by gravi-ty; but it being remembered that there is a partial vacuum below the f piston K the sleeve can descend only as air is admitted to this space. Air can come to this space only thro-ugh the stem I, the ingress of air being regulated, as explained, by previously setting the cap T. As the air enters the space below the piston the sleeve L will descend. As

the cup R enters the valve-,seat the sleeve is brought to rest slowly and the closing off of the water from the pipe B will be gradual instead oi being closed oit with a shock.

It will be obvious that the construction oi' the various parts may be varied without departing from the spirit of my invention.

rIVhat I claim, and desire to secure by Letters Patent, is-

l. The following instrumentalties in operative combination, to' wit: the rods G G, the

yoke II connecting the rods, the stem I, sleeve J and piston K suspended from the yoke, the sleeve L surrounding the stem, sleeve and piston, the yoke-hanger suspending the sleeve L, and the operating-lever 6, substantially as described and for the purposes set forth.

In a water-closet-ilushin g apparatus, the combination of the following instrumentalities, to wit: a tank, an overflow thereto, an

outlet-pipe B for the tank communicating f with the flushing-pipe, a valve-seat, a movable sleeve L, cooperating with the valve-seat to control the llowof the water therethrough, a stationary piston entered into the sleeve and having a hollow stein and wing-guides to guide it in its movement in the sleeve, the said stem being externally screw-threaded and having a screw-threaded cap carried thereupon .for regulating the inlet et air to the stem; conibined with means for supporting and operating the herein mentioned operating parts comprising the rods G G, the yoke Il connecting the rods and supporting the hollow-stein Wing-guides and piston, the yoke-han ger suspending the sleeve L, and the operating-lever G, substantially as described and for the purposes set forth.
